Hypnosis is not like sleep: it was named Hypnosis after Hypnos, the Greek god of sleep, but that’s just because it looks sort of like sleep to people watching. You’re always able to be as aware as you need to be. Read the section on “Is Hypnosis Mind Control?”

No. No, it can’t. Just like above, hypnosis can’t make you do something you wouldn’t want to do: it just doesn’t work that way. It wouldn’t matter either way anyway, as everything you say will be 100% confidential.

Yes, basically. It used to be thought that only 10-15% of people could be hypnotized, but we’ve come a long way since then. We now know that anyone of basic or above intelligence who’s willing to follow instructions can be hypnotized.
